Modular Head Shop - Comp 3V Thumpr NSR Cams

The Comp Cams 3V Thumpr NSR Camshafts are designed to be rowdy and have a nice muscle car lope at idle. These Camshafts offer good midrange and upper RPM gains and can be used with the stock valve springs. They do require Comp Cams Phaser Limiters but can still be used with the factory VCT.

If you need help selecting a camshaft for your application, whether it be N/A, Blower, Nitrous or Turbo, we will be happy to help. Please send us an email at ModHeadShop@gmail.com with as many details on your current setup and your overall goals.
